Built from vanadium high speed steel with a TiCN (titanium carbonitride) coating, this bit delivers extended tool life and improved wear resistance compared to standard uncoated HSS drills. It measures 4 mm in diameter with a 75 mm overall length and a 43 mm flute length. The 120-degree split point with X-thinned web reduces walking and decreases thrust force at entry, making it effective for precision work in ferrous and non-ferrous materials.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for drilling in steel, alloy steel, stainless steel, cast iron, aluminum, aluminum alloy, and aluminum silicate. Typical applications include blind hole drilling, cross hole drilling, through drilling, and self-centering operations. The straight-cylindrical shank fits standard drill chucks on CNC machines, drill presses, and handheld power tools. It is well-suited for use in job shops, maintenance facilities, and production environments where consistent hole quality in mixed materials is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiCN coating increases surface hardness and reduces friction for longer tool life in steel and cast iron\u003c\/li\u003e\n\u003cli\u003eX-thinned web point reduces entry thrust and improves self-centering performance\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute design promotes efficient chip evacuation in deep-hole applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with 2 flutes and tapered web configuration for balanced cutting geometry\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of plus 0 to minus 0.018 mm for consistent hole sizing\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit jobber-length drill bit for use in any standard drill chuck or collet accepting a 4 mm straight-cylindrical shank. Rated for primary workpiece material codes P, M, K, and N covering steel, stainless steel, cast iron, and non-ferrous materials.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by a machinist or maintenance technician into a drill press, CNC machining center, or handheld drill with an appropriate chuck or collet. Secure the shank fully before operation and verify chuck runout is within acceptable limits to protect the cutting edge. No coolant-through capability is present on this bit, so apply cutting fluid externally when drilling stainless steel or cast iron to manage heat buildup. Inspect the cutting edge for wear or chipping before each use and replace if the TiCN coating shows significant depletion at the tip.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4 mm (0.1575 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 75 mm (2.953 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 43 mm (1.693 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 120 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: X-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Vanadium High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: plus 0 to minus 0.018 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1800\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8594040\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51729190289714,"sku":"8594040","price":32.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6114427d051636e98bf96d2e9c8e53a9.jpg?v=1788701691","url":"https:\/\/voomisupply.com\/products\/osg-8594040-jobber-drill-bit-4-mm-ticn-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
